Patented Sept. 16, 1930 PATENT OFFICE GEORGE H. EARMAN, F HARRISONB'UBG, VIRGINIA MEANS FOR REMOVING ODOR AND FLAVOR OF GARLIC FROM MILK l.llpplcaton filed May 7,

It is well known that in the spring season garlic grows profusely in the fields and pastures and cows. grazing therein eat the garlic Vwith the grass so that the milk produced is A strongly tainted with the odor and flavor of garlic which is very obnoxious to a great Vmany people. The odor and flavor of garlic is carried into butter produced from the milk, making the butter distasteful. It is the ob- 1,0 ject Vof the present invention to provide sim ple means whereby the odor and flavor of the garlic will be removed from the milk and the milk rendered palatable to all persons. The `object of the invention is attained in such a mechanism as is illustrated in the accompanying drawing, and the invention resides in certain novel features which will be particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a sectional elevation of an apparatus embodying the invention, and

Fig. 2 is an enlarged longitudinal section through a portion of the conduit through which the milk is caused to circulate.

In carrying out the invention, there is provided a reservoir or tank 1 which may be of any suitable material and of substantial proportions so that it will contain a large quan- This tank is provided with a clean out opening 2 at or near its bottom and upon the top of the tank is supported a bracket or spider 3 consisting of radially extending arms provided with v,down-turned ends 4 whereby they are adapted to rest on the edge of the tank or reservoir and fit against the outer wall thereof so thatV lateral movement will be prevented.

The inner ends of the arms are turned upwardly and meet in a central hub 5 within which is fitted a coupling sleeve or body 6 having an annular groove 7 in its external surface and having a port or passage 8 formed through its inner end to establish communication with said annular groove at one side thereof. The inner end of the coupling body 6 is externally threaded, as shown,

whereby to be engagedwith the wider end of an inlet nozzle 9 having a central bore 10 leading tothe port 8, as clearly shown in Fig. 2. To the outer end of the nozzle 9 is coupled one end of a blow pipe 11 which forms the outlet from a fan or blower 12 of any approved form. The nozzle 9 is externally tapered, as clearly shown, and its smaller en-d receives a. coupling collar 13 whereby a slip joint connection with the blow pipe is formed. The coupling body 6 is also tapered outwardly and a slip joint coupling collar 14 is connected therewith to hold to o0 the coupling body one end of a circulating pipe 15. It will be noted that the end of the coupling nozzle 9 abuts one end of the hub 5 and that an annular shoulder 16 is formed on the coupling body 6 to abut the 65 opposite end of the hub whereby the parts will be firmly assembled when the nozzle 9 is turned home, the hub being clamped between the end of the nozzle and the shoulder 16 is an obvious manner. Lead- 70 ing from the annular groove 7 to and through the reduced end of the coupling body v6 are ports 17 which are of restricted diameter and are provided in any desired number in converging relation so that they are brought close together at the discharge or reduced end of the body, a small nipple 18 being formed on the end of the body within the circular series of ports. 17, as shown in Fig. 2. The coupling body 6 is also formed with 80 a central bore or passage 19, the inner end of which is much larger than its outer or discharge end, the bore or passage gradually reducing in diameter toward its discharge Serial No. 361,134.

end, which end extends through the small 8FV nipple 18. In the side of the coupling body is an opening communicating with the inner end of the bore 19 and receiving the upper end of a pipe 2() which depends therefrom into the tank or reservoir and terminates near the bottom of the same. The circulating pipe 15 has its bore enlarged to form a chamber 21 at its receiving end around the discharge ends of the passages 17 and the bore 19 and from the outletl side of this chamber a reduce-d 5 culating pipe extends down alongside the 100.y

tank 'and its lower end is carried through the v side of the tank immediately abovethe biottom thereof and provided With a large num# ber of perforationsQl through Which the air and milk may escape. For convenience in assembling the parts, the perforated terminal ofthe circulating'pipe is formed 'as a separate member and a coupling 25 is provided to connect the ysame with the main section of the pipe;l l Y o In use, the tank is i'illed or`nearlyilled i r*with the milk, as indicated at 26. The parts Y being assembled as shown and described, the
